A. Platelet deposition around microspheres was significantly lower compared to GTKO islets (1hr p=0.03, 24h p=0.02). Over the 24 hour period there was little change in both microspheres (p= 0.13) and GTKO islets (p=0.74).
B. Obstructive embolus consisting of multiple microspheres with platelet clot formation at one hour.
C. A single microsphere at the proximal end of a sinusoid with minimal platelet involvement at 24 hours.
D. GTKO islet cluster with surrounding platelets at one hour.
